Girder installation delayed at St. Johns

The installation of large support girders at the intersection of state Highway 500 and St. Johns Boulevard will be delayed until at least next week, the Washington State Department of Transportation announced.

WSDOT is converting the intersection into a freeway-style interchange in which St. Johns will pass over Highway 500 on a new bridge. Steel girders — measuring as long as 250 feet — will support connecting ramps from the highway.

Crews had planned to begin installing the girders Friday. But during a final review of the work site this week, the contractor identified one temporary support tower that needed adjusting, according to WSDOT. That meant project planners had to reschedule construction cranes, which are typically in high demand.

The girder installation will be delayed by at least three days, according to WSDOT, which would push the start of the process into next week.

Officials said the change won’t affect the $48 million project’s overall schedule. It is slated for completion in 2013.
